3 Claims, 6 Drawing Figures PATENTEUJANZ 9 I974 SHEEI 2 BF 2 FiGfi FIGSFIELDS OF THE INVENTION There are two kinds of reels for fishing, theone is a drum-type reel and the other is a spinning reel. The

former is expensive because it is large and its mechanism iscomplicated. On the'contrary, the latter is inexpensive because it issmall and the mechanism is comparatively simple. Therefore, the latterhas been used more widely.

The reel of th'is'invention is directed .to the latter, i.e the spinningreel, comprising a main body and a rotor or revolving assembly. Therevolution of a handle on the main body is transmitted to the rotor byengaging a crown gear with a pinion, and a fishing line is wound on aspool which is installed within the rotor and moves back and forth. Theline can be extended by hanging it on a bailarm roller which is placedat the wall of the rotor.

THE PRIOR TECl-INIQUE OF THE INVENTION Generally, to make a-spinningreel, a pinion to transmit the revolution of a handle to a rotor and therotor itself are made separately. The pinion is fitted in a hole at thecenter of the rotor to be fixed on the revolving side, fitted in theinside of a main body to make it engaged with a crown gear, and then, toprevent the pin ion to slip out of the main. body, fitteda check platein a loop slotof the pinion which is at the side of the rotor and fixesthe check plate to the main body by screws. Therefore, the reelhassdefects that not only the fabrication is complicated because highaccuracy is required in the centering'of the rotor and the pinion,

but also the reel tends to become cranky during theoperation.

In the system of transmitting the revolution of a handle to a pinionwith a crown. gear, a pipe axis is attached to the crown gear, and thecrown gear is kept in a fixed position by fitting the pipe axis to along and slender axis, one end of which is fixed on the handle. Sincethese parts are-made of different material and hence the expansioncoefficients are different, mutual fitting becomes necessary and wastesdue to the complicated manufacturing process and to the production ofinferiority goods are large. And also, if we want to inake the mutualfitting unnecessary, excessive accuracy is required in manufacturing andhence the cost becomes high. Furthermore, in a bail arm roller assemblybooking a line, the inside of a metalic roller is bored and therevolvingforce of the roller is made large by supplying the lubricatingoil to the bored hole and make'the frictional coefficient between theroller and the axis small. Such a system, however, has a defeet that,while fishing, the water sticking on a fishing line is poured in thehole and lets the lubrication oil go out. Since the roller and the axisare both metaL'if there is no lubrication oil between them, they tend toburn and make the load large and the revolution becomes impossible andthus make the. winding operation difficult and non-smooth resulting inloss of fish.

THE OUTLINE OF THE INVENTION This invention is an improvement to removethe abovementioned defects.

One of the objects is, therefore, to simplify the manu facturing andassembling process and make mass production possible to supply fine andcheap reels.

Another object is to make a crown gear transmitting a revolution of ahandle to a rotor and pipe axis to be attached to an axis of a crowngear as a unit form by a metal type for casting and thus to produceuniform products in a large scale, whereby fine reels are supplied whichare low-priced and interchangeable, and which have beautiful appearanceand which do not need secondary work.

A further object is to supply inexpensive bail arm rooler assemblieswhich maintain smooth revolution without being influenced by watersticking on a line.

DETAILED EXPLANATION OF THE INVENTION This invention relates to animproved spinning reel for fishing which has a bail fixed to a rotor orrevolving assembly by a bail hinge so that the bail can be rotatedfreely, and in which transmittion of the revolution of the handle to therotor is made by a crown gear. In this reel, a pinion, a gear pipe, witha slot around the leading edge of the pinion, and rotor are made as oneintegral unit. After fitting the gear pipe inside a main body, a stopperplate is inserted in to the slot in the gear pipe and a matching slot inthe main body so that the gear pipe is secured in the main body and canrotate freely. Further, a pipe axis with polygonal internal section andthe crown gear which is adapted to engage the pinion, are made as oneunit. A polygonal axis which is fitted to the handle is inserted in thepipe axis. In the hole drilled inside the roller of the bail, axisholder of oilabsorbent synthetic resin isfitted and constitutes the axisholder of the axis which is attached to the closing section as one body.Thus, the present invention relates to a spinning reel with theabovementioned characteristics. I

Detail description is made hereafter by referring to the drawingsshowing the embodiments of this invention.

Reel A, from the top of which a foot 1 is sticking out and a rod 2 isfixed on it, consists of a main body 3 and a rotor 4. A crown gear 5which is located in main body 3 is mounted to one end of axis 6 and ahandle 7 is attached to the other end of axis 6. Pinion 9 which formsone end of gear pipe 8, engages the crown gear 5 and thus therevolutions of handle 6 are transmitted to the gear pipe 8 via axis 6,crown gear 5 and pinion The rotor 4 is hollow and the one side thereofis open at 4a and the other side is closed by a side wall 10. Around thecenter of the side wall 10, there is a round dented section 11 which isconvex inside and at the center of which the gear pipe 8 extends. Therotor 4 and gear pipe 8 are integrally composed as one unit by a castzinc-alloy or the like. On one end of the gear pipe 8 a pinion 9 is cutand around the leading edge of the pinion 9 a loop slot 12 is cut sothat a stopper plate 13 can be inserted. An axis hole 14 is at thecenter of the gear pipe 8 and a reel shaft 15 is fitted so that it canmove back and forth freely. The gear pipe 8, pinion 9 and reel shaft 15are offset from the axis 6 so that the desired motion can beaccomplished. The teeth of the crown gear 5 are cut at an angle to itsradial direction and correspondingly, the teeth on the pinion 9 are cutat an angle to the axial direction of the pinion. Since this arrangementwell known in the art, no further explanation will be made. Further, onone side of the main body 3, a guide section 17, connected at a necksection 16, is formed in one unit with the main body 3 itself, and aslit 19 is formed by cutting one side wall of the neck section 16 whichhas an axis hole 18 at the center. Therefore, the rotor 4 can beconnected to the main body 3 so that the former is rotatable freely byinserting the stopper 13 through the slit l9 and fixes to the slot 12 ofgear pipe 8 after inserting the gear pipe 8 into the axis hole 18 andthe round guide section 17 is placed in the round dented section 11.Since the main body 3 and the rotor 4 can be easily assembled ordisassembled by fixing or separating the stopper 13, assembly in theplant, pouring of lubricant and disassembly after the use of reel andthe inspection of the inside mechanism are very convenient. As thepinion 9 is formed integrally in one unit with the rotor 4, it does notbecome cranky during the operation, and it is not necessary to reformthe teeth of pinion 9 for each instrument since they are made by metaltype for casting on which teeth are formed by a precision machine. Thecomplicatedness of the manufacturing process and the assembly process ofreel is dissolved and simplified, thus it becomes possible to producehigh quality and inexpensive reels in a large scale.

Furthermore, the crown gear 5, which engages with said pinion totransmit the revolution of handle 7 to the rotor 4, is made in one unitwith the pipe axis 20 integrally, which has a polygonal internal section20a which extends above and below the crown gear 5 by a proper length.The unitary crown gear 5 and pipe axis 20 is fixed to the polygonal axis6 which cross perpendicularly to the gear of the axis-pipe 8 and offsettherefrom which is laid between the side wall 3a and the cover 3b of themain body 3. The edge 6a protrude from the axis hole 21 of the cover 3band has the handle 7 fixed thereto by pin 22. In doing so, the polygonalinternal section 20a of the pipe axis 20 and the polygonal axis 6 are tobe engaged with each other and rotate as a unit.

The other end 6b of the polygonal axis 6 is fitted by screws 23 to theside wall 3a of the main body 3 so that it can be rotated freely. As thecrown gear which transmits the revolution of the handle 7 to the rotor 4and the pipe axis 20 with the polygonal internal section which fits thecrown gear to the axis 6 are made as one unit by metal type for casting,the products are uniform and mass production is possible, and they areinexpensive and mutually interchangeable, have beautiful appearance, anddo not need secondary work. Further, the complexity in assembling andthe secondary work to fit the parts mutually in each product are omittedand the number of the inferrior goods is decreased resulting in decreaseof the cost and production of quality goods.

An eccentric cam 24 is secured to eccentric sleeve 40 of axis pipe 24and is connected to reel shaft 15 by pin 41. The reel shaft 15 is shownpartially extended in FIGS. 3 and 4 and consequently eccentric sleeve 40appears centered in these sectional views. The translation of angular tolinear oscillatory motion using an eccentric sleeve is well known. Thespool 26 is fixed by a drag knob 30 to the end of the reel shaft 15 andis located within the rotor 4. The spool 26 includes a front wall 26aand a back wall 26b between which the line is wound. The back wall 261;has a nail 28 on its back and a spring 28a which engages a gear 29 whichis fixed to the reel shaft 15 by a pin 25. By the revolution of thehandle 7 and by the following revolution of the eccentric cam 24, thereel shaft 15 moves back and forth and the spool 26 moves in and out therotor 4 through the opening 4a, thus the line 27 can be wound to bespool 26 by hanging the line 27 to a roller 31 of a bail arm rollerassembly B equipped on the wall of the rotor 4. A bail 32 of the bailarm roller assembly B is assembled to work freely through a bail hinge33 on a wall of the rotor 4. The roller 31 is arranged rotatably aroundan axis 35 which is fitted as one body with a closing section 34 whichin turn is fixed to the bail 32. Inside of the roller 31 a hole 36 isdrilled and axis holder 37, which is made of oil-absorbent syntheticresin with a drilled hole at the center, is fixed to said hole 36 bypressure insertion to form the axis holder of the axis 35. The axisholder 37 mates with the lower section of bail hinge 33 and-the closingsection 34. This axis holder 37, being oil-absorbent material, does notneed the oil supply and smooth revolution is always expected.

Therefore, at the time of fishing, hook a line on a bail arm 38 equippedon the bail hinge 33 and revolve the handle 7, which rotates the rotor 4together with the bail hinge 33, and the line 27 is wound to the spool26 by the back and forth movement of the spool 26. The line 27 can becast from the spool 26 by unhooking the line from the bail arm 38 byrotating it. During winding the line 27, although the water sticked onthe line flows.

into the axis holder, the burning, i.e., the largest defect of theconventional reel, can be avoided as the axis holder 37 is anoil-absorbent synthetic resin. Thus, there appears no influence on thepower of revolution of the roller 31 and the winding operation of theroller. There is also an advantage that the cost of the axis holder 37in this invention is low compared with the conventional axis holder madeof super-solid alloy or the like.
